The present invention has no special limitation to the source of the raw material used above, can be general commercially available.
The present invention provides a kind of ethanol gasoline detergents, are prepared by the raw material comprising following parts by weight of component: poly-
10~30 parts of isobutene imidazoline；0.5~1 part of alcohol compound；2~10 parts of anti-knock agent；0.01~0.05 part of antioxidant；Solvent
67.9~89.4 parts of oil.It has been found that compared to polyisobutylene amine, the imidazoline ring of polyisobutene imidazoline be easier so that
Lone pair electrons on nitrogen are adsorbed on engine metal surface, increase the contact area and absorption of detersive and engine metal surface
Ability effectively promotes detersive to the protecting effect of engine, hence it is evident that reduce deposit generating rate.Meanwhile polyisobutene miaow
Oxazoline also prevents the effect of corrosion, and polyisobutene imidazoline cooperates other components synergistic effect, obtains ethanol gasoline detergent,
The ethanol petrol oil product for adding this ethanol gasoline detergent is peace and quiet, and pollutant emission is less, and oil consumption is lower, efficiently solves second
Alcohol gasoline corrodes harm to the burn into of engine, maintains the permanent working condition of engine.
In the present invention, add the ethanol gasoline detergent ethanol petrol can significantly reduce engine nozzle, into
The deposit of air flue and combustion chamber keeps engine washing, and engine long period is made to maintain new car state；It is able to ascend gasoline combustion
Expect utilization rate, saves oil consumption；It can reduce exhaust emissions, protect environment；It is able to ascend petrol power performance, accelerating ability subtracts
The generation of few phenomenon of detonation.The antioxygenic property for adding the ethanol petrol of the ethanol gasoline detergent gets a promotion, oil product storage
Stability enhancing is deposited, the shelf-life increases, and Loss of Oil Products at Gas Station replacement frequency and replacement cost is effectively reduced；To the corrosivity of engine
It reduces, extends engine using the time, reduce maintenance, the replacement cost of engine；Phase stability gets a promotion, and extends
Storage time reduces transportation cost.
The experimental results showed that adding the E10 ethanol petrol of the ethanol gasoline detergent compared to E10 ethanol petrol
Rate of economizing gasoline is above 7%, and oil consumption is lower；The deposit rate of descent obtained using gasoline engine simulation inlet valve deposits test method(s) is equal
It has been more than 95%, has been more than 94% using the deposit rate of descent that M111 bench test method obtains, oil product is peace and quiet；Meanwhile this
CO, HC compound of the ethanol petrol of invention reduce obviously, and rate of descent of the rate of descent not less than 30%, HC of CO is not less than 50%,
It is significant to reduction discharge, protection environment；Also, the rust-preventing characteristic of ethanol petrol is obviously improved, and phase stability, which extends, is not less than 3
A month, oxidation stability extend be not less than 4 months, therefore, have in terms of product stability, oxidation stability, rust-preventing characteristic compared with
Excellent effect.
